The general ethoxalylation procedure for the synthesis of isoflavones has been applied to the synthesis of irigenin (VII) and tectorigenin (XVI). This synthetic route also yields the isomers, ψ-irigenin (XI) and ψ-tectorigenin (XX). Information concerning the product ratio in certain ethoxalylation reactions and the relative thermodynamic stabilities of 5,6,7- and 5,7,8-trisubstituted isoflavones is
合成异黄酮的一般乙氧基化方法已应用于合成irigenin(VII)和tectorigenin(XVI)。该合成途径也产生了异构体,ψ -irigenin(XI)和ψ -tectorigenin(XX)。讨论了有关某些乙氧基化反应中产物比例以及5,6,7-和5,7,8-三取代异黄酮的相对热力学稳定性的信息。
